SUPPORT FOR SWINGING CLOSURES.

Application led October 21', 1925.

The present invention relates to supports for closures; and its object is to provide improved means for supporting a horizontally swingable closure at a point offset from the axis of its mounting.

This and any other and more specific objects hereinafter appearing are attained by, and the invention iinds preferable embodiment in, thcfstructure hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which Figure 1 is a top plan View of the horizontally-swingable closure of a furnace door and connected parts;

Figure 2 is a front view of the same, showing our support applied to the closure;

Figure 3 is a side view, partly sectioned axially, of a form of said support;

Figure 4 is a top plan view, similar to Figure 1, but showing a. modified construction;

Figure 5 is a side view, similar to Figure 2, but showing said modified construction;

Figure 6 is a longitudinal sectional view of a device holding adjustably-slidably a socket member receiving the lower end of the support; and

Figure 7 is a view in perspective of a portion of said socket member.

Vhere closures swingable on a vertical axis are heavy, or where they carry heavy part-s, they are liable to sag downwardly at their free ends. The object of this invention is to provide improved means for obviating this difficulty.

In the accompanying drawings is shown a closure 1 mounted swingably on a vertical aXis-the hinges 2-and adapted to close the door 3 of a furnace indicated at 4. In this particular construction the closure carries heavy parts, as our oil-burning apparatus indicated at 5, certain parts of which indicated at 6 and 7 extend through the closure and into the furnaces interior. The showing of said parts 5, 6, 7 is however incidental for such parts merely indicate eXtensions and heavy parts carried by the closure and forming portions thereof.

The support in preferable form is illustrated in Figure 3, and is a longitudinallyexpansible rod, designated generally 8, comprising a tubular upper portion 9 and a lower portion 10 slidable therein in the rods ASerial No. 64,063.

longitudinal. direction, a spring l1 in the tubular portion pressing against its plug 12 and the upper end of portion 10 to urge said portions 9 and 10 from each other thus expanding the support or rod 8 longitudinally. The lower end of the rod 8-i. e., the rounded extremity 13 of the lower portion -10-is mounted turnably and removably in an open socket 14 in the socket member 15 secured to the licork 16, as by a screw 17.

The upper end of the rod 8-i. e., the round- Y from sagging downwardly.

The lower socket 14 may also be offset horizontally from said axis 2 of the closures swinging movement as indicated, and so placed as to urge the closure in one or the other direction of its swinging movement as may be desired.

In the modified construction illustrated by Figures 4, 5, 6 and 7, the lower end of the rod 8 is supported by a socket member 151 comprising the nut portion 21 and the portion 22 threaded at 23 in the nut portion and having in its head the open socket 14 removably and turnably receiving the rounded lower end 18 of the rod, the upper end of the rod being received in the socket 19 of the socket member 2O positioned preferably adjacent the middle and front of the closures under side. This socket member 151L is held, by its lateral ribs 24 engaging beneath the arms 25, 25 of a fixed element 26, in adjusted position in a slide bearing 27 in said element when the portion 22 is tightly screwed down in the nut portion 21, to thus adjust as desired the position of the lower end of the rod 8.

The invention being intended to be pointed out in the claims, is not to be limited to or by any details of the construction of the particular embodimentthereof illustrated by the drawings or hereinbefore described:

l/Ve claim:

1. In a structure of the character described: a closure mounted sWingably to open and closed positions on a vertical axis: a support therefor comprising a longitudinaily-expansible rod mounted swingably at its lower end and supporting at its upper end the closure at a point oiiset from said axis; means for yieldingly expanding the rod.

2. In a structure of the character described a closure mounted svvingably to open and closed positions on a vertical axis: a support therefor comprising a longitudinally-expansible rod mounted swingably at its lower end at a point offset from said axis and supporting at its upper end the closure at a point oiiset from said axis; means for `yieldingly expanding the rod.

3. In a structure of the character described a closure mounted swingably to open and closed positions on a vertical axis: a support therefor comprising a rod having a tubular portion and a portion slidable therein, one of said portions supportingly engaging the closure at a point oiiset from said axis and the other of said portions being swingably mounted; a spring intermediate said portions pressing the same from each other.

4. In a structure of the character described, a closure mounted swingably to open and closed positions on a vertical axis: a

support therefor comprising a rod having a tubular portion and a portion slidable therein, one of said portions supportingly engaging the closure at a point offset from said axis and the other of said portions being swingably mounted at a point oiiset from said axis; a springintermediate said portions pressing the same from each other.

5. In a structure of the character described: a closure mounted svvingably to open and closed positions on a vertical axis and having an open socket offset from said axis: a support therefor comprising a rod having a tubular portion and a portion slidable therein, one et' said portions supportingly engaging removably in said socket; an open socket removably supporting the other of said portions turnably; a spring in said tubular portion pressing said portions from each other.

6. In 'a structure of the character described: a closure mounted swingably to open and closed positions on a vertical axis: a support therefor comprising a longitudinally-expansible rod supporting at its upper end the closure at a point otfset from said axis; a ixed element having a slide bearing; a socket member slidable in said bearing and supporting the lower end of the rod; means for securing said member in adjusted position in said bearing.

In testimony whereof We have hereunto set our hands at Dowagiac, Michigan, this 13th day of October,.l925.
